BRAIDING-CARRIER.

T o all whom it 'may concern:

Be it known that I, PAUL BUTLER, a citizen of the United States,residing at Lowell, county of Middlesex, and State of Massachusetts,have invented an Improvement in Braiding-Carriers, of which thefollowing description, in connection with the accompanying drawing, is aspecification, like characters on the drawing representing like parts.

This invention has for its object to provide a novel braiding carrier.

The features wherein my invention resides will be described in theannexed specification and will then be pointed out particularly in theclaims.

This application is a division of my copending application Serial No.659,888, filed November 26, 1897.

Referring now to the drawings: Figure 1 is a vertical sectional view ofa braiding carrier embodying the invention. Fig. 2 is an enlargedcentral section through the upper end of the braiding carrier. Fig. 3 isa top plan view. Fig. 4 is a fragmentary, sectional view of a braidingmachine showing the manner in which my improved braiding carrier issustained therein. Fig. 5 is a perspective view of the stoppin used inconnection with the braiding carrier.

The braiding carrier as herein shown consists of the two top and bottomends ft and f5 which are connected by the opposite arms or side piecesf6. The ends or cross pieces f4 and f5 have the hubs or journals f and fprojecting therefrom` which are adapted to be received in notches in thecarrier plates E, all as shown and described in my said copendingapplication. I prefer to provide the hubs f f with anti-friction sleevesf3@ and f31 which are loosely mounted on the hubs, and which serve toreduce the friction between the hubs and the carrier plates. The yarnmass is sustained by a central spool or bobbin r having a base or head1" which rests on the lower cross piece or end f of the bobbin carrier.This spool is held in place by a spindle r2, the lower end of which isreceived in a recess f2 in the hub f', and the upper end of whichextends into an opening f3 formed through the cross piece f5 andextending on through the hub f. It will thus be seen that the spindle r2is sustained at both ends but that the spindle may be lifted to projectthe upper end into the opening f3 Specification of Letters Patent.

Original application filed November 26, 1897, Serial No. 659,888.

Patented Nov. 28, 319212.

Divided and this application iiled April Serial No. 558,333.

suliiciently to admit of the lower end being withdrawn from the recessf2. This makes the removal of the spindle or its insertion into place avery simple matter. The thread from the yarn mass is delivered throughthe passage f3, and I preferably provide a guidering r3 which restsloosely on the cone n of the thread mass and which prevents the threadfrom ballooning and serves to guide it in its delivery from the cop orbobbin.

Associated with the bobbin carrier is a tension device which comprises afriction member t provided with a vertically-extending friction face 2Oand a spring-pressed tension finger t which is adapted to bear againstsaid face. This friction member is rigid with the carrier and may beplaced in any appropriate position. I have herein shown it as sustainedby a plate 21 at the upper end of the hub f and in position so that thethread on leaving the passage may pass over the face 20 thereof.

The tension finger t is mounted for turning movement upon a stud t5which is carried by the braiding carrier, and said finger is acted on bya suitable spring 159 which tends to hold it against the friction membert. This spring is shown as coiled about the stud and one end 251 thereofis bent to engage the tension finger t', while the other end is securedto a nut or collar 156 that is screw-threaded on the end of the stud.This nut or collar t is held in adjusted position by a lock nut t7. Itwill readily be seen that the tension of the spring and, consequently,the friction on the thread may be adjusted by adjusting the nut t,

As the thread is delivered from the bore f3 it passes up over the faceQ0 of the friction member 15, thence up over the top of Vthe tensionlinger t and around a fixed post or linger t2, and thence back betweenthe tension finger and the friction member t again if desired, and fromthence directly to the cord being braided, or to a guide t* which may becarried by the stud 155 and thence to the cord. The thread may be passedbetween the friction member t and the tension linger t as many times asnecessary to get the desired friction on the thread.

I have herein shown a stop pin u provided with a thread-receiving grooveu and with a collar um. This stop pin is received in a suitable aperturein the friction member. The thread is shown as operating the groove u inthe stop pin, and as long as the thread remains unbroken the tension ofthe thread is suiiicient to hold the stop pin in its ele vated position.If the thread breaks, however, the pin will be permitted to drop untilthe collar u meets the member t which leaves the lower end of the pin inposition to engage a stop device, all as more fully described in myco-pending application.

It is not essential to my invention that the tension device be situatedat the upper end of the hub as the hub might extend beyond the tensiondevice if desired.

I'Iaving fully described my invention what I claim as new and desire tosecure by Letters Patent is:

l. A braiding carrier having top and bottom cross pieces united by arms,the bottom cross piece being adapted to receive and carry abobbin-retaining spindle and the top cross piece having a centralaperture fo-rming a thread passage and a bobbin spindle having its upperend projecting above the thread Vmass and into said passage the latterserving to hold said upper' end in position.

2. In a braiding carrier, the combination with a frame having outwardlyprojecting hubs at its top and bottom ends, of anti-friction sleeves onsaid hubs, and a tension device carried by the carrier and comprising afriction member, a post separated therefrom, anda tension fingersupported yieldingly to vibrate between said member and post andnormally held under pressure against the member.

3. In a braiding carrier, the combination with a fra-me having outwardlyprojecting hubs at its top and bottom ends, of anti-friction sleeves onsaid hubs, and a tension device carried by the carrier and comprising afriction member, a post separated therefrom,

atension linger supported yieldingly to vibrate between said member andpost and normally held under pressure against the member, and means tovary the pressure of the tension iinger against the member.

4. In a braiding carrier, the combination with a frame having hubs atits top and bottom ends and means to support a thread mass and providedat its upper end with a thread passage which extends axially through thetop hub, of a tension device sustained by the frame and comprisingafriction member at the terminus of said thread passage over which thethread passes, a pivoted tension finger yieldingly held against themember, and means to vary the pressure of the finger on the member.

5.'In a braiding carrier, the combination with a frame having astatio-nary friction surface, of a post separated from said surface, atension arm supported yieldingly by;

the frame to vibrate between said surface and post and normally heldunder pressure against the former.

G. In a braiding carrier, the combination with a frame having astationary friction surface and a post separated therefrom, of a studsupported by the frame, a tensionarm pivoted on said stud, a coil springmaintaining said arm in yielding engagement with said surface, andk aneye on said stud y whereby the twine may be passed between said arm andsurface about saidV post and through said eye.

In testimony whereof, I have signed my name to this specication, in thepresence `of two subscribing witnesses. y
